We can connect to the physical world with Mqtt and Home assistant. And through that to 3500+ other worlds.

This is an exploration, demonstration and explanation.

We'll see FM, Mqtt, Raspberry Pie, Home assistant, CO2, proximity, phone tracking, weather, Matter, Thread, ESP32, Python … 3500+.

Well … it doesn't work yet. So it's gonna be only a sneak in this unpresentation ! With the Pico.
